Juan Gonzalez:
Is the same problem as this one?:
https://issues.liferay.com/browse/LPS-42908
In that case, you have to patch your Liferay source code using the github commits from that LPS.
Thanks for the answer. It wasn't that case but i found the problem. In my case was the permissions of the Guest Role Over the tags. By default, Guest Role don't have view permission over tags, so if you try to filter usings tags, Liferay won't filter for Guest Role and will show all the contents. To solve the problem you have to activate the configuration of permission for tags, that is desactivate by default too. To do that, you have to add this lines
asset.tag.permissions.enabled=true
asset.tag.properties.enabled=true
to the file portal-ext.properties, that is in the tomcat root. It you don't have itm you create it with this two lines. Then you only have to go where the tags are define, you will find out that the are two new buttons, and give view permission for Guest Role for every tag you want to use to filter content.
